Hitachi Communication Technologies America Announces 10GEPON They will show DOCSIS Managed 10GEPON at Cable Industry Event

SANTA CLARA, California, May 11, 2010 - Hitachi Communication Technologies America, Inc. (HCTA), the only vendor offering a comprehensive line of EPON, DePON™, MW-PON™, and RFoG equipment, today announced the availability of 10GEPON and 10G DePON Optical Network Units and Line cards for the Salira product line. These new offerings give cable operators a fiber access infrastructure capable of supporting the bandwidth needed for today's applications. HDTV, 3DTV, videoconferencing, cloud computing, rich media files, gaming, transparent LAN services, MEF services, and other business applications are straining existing access technologies. Increasing bandwidth with other solutions has proven expensive for use in wide-scale deployments. However, Hitachi's 10Gbps DePON offers the combination of high bandwidth, lower cost, and effective service control required for profitable high-volume business and residential services.

HHCTA's pioneering work on integrating DOCSIS™ management with the IEEE GEPON physical layer has paved the way for DOCSIS control of this new 10Gbps infrastructure. Reusing DOCSIS management with 10Gpbs fiber access is part of Hitachi's strategy of leveraging existing standards based equipment for an efficient migration from HFC to fiber access. The IEEE 802.3av standard supports symmetrical 10Gbps transmission or 10Gbps downstream and 1Gbps upstream. The wavelengths used in 10GEPON are allocated with the goal of ensuring coexistence with existing GEPON and RF video to enable support for symmetric 10Gbps ONUs, asymmetric 10Gbps/1Gbps ONUs, and symmetric 1Gbps ONUs, as well as radio frequency (RF) video overlay on the same optical distribution network.

Hitachi equipment supports one of the largest cable operator based EPON networks in the US. Experience with this deployment shows that 10GEPON offers the bandwidth and density capable of supporting the services that business and residential subscribers demand at a cost that justifies the investment. Hitachi is a contributor to the IEEE 10GEPON standard and has a leading role in SIEPON and other standards efforts aimed at integrating DOCSIS and EPON as well as creating interoperability of EPON equipment.

"We believe that Hitachi's 10G-DePON will become the primary technology for cable operators building new high bandwidth access networks." said Takashi Mori, president of the Salira Division of HCTA. "It has the bandwidth and features our customers need to create services today and in the future." he continued.

HCTA will show 10G-DePON in booth #759 at The Cable Show in Los Angeles, May 11-13, 2010. The company will also provide a live demonstration of DePON at the CableNet showcase.
